Downscaling and modeling natural disturbances such as the extratropical storms are important for understanding predicting behavior of air flow over complex forested areas, especially in high wind instances that cause damages. Therefore, rationale research was windscape a storm could be reconstructed based on features consequent forest windthrows. Main input data model were derived from damages (extension, orientation, depth windthrows) retrieved combined UAV imagery, high-resolution field survey, integrated with terrain, at stations within study area, land cover, overturning breaking point conditions tree species, human interventions. Using GIS environment, critical speed index calculated, well main direction each damaged stand, considering factors lead to This then compared computational fluid dynamics built WindNinja app, using conservation mass momentum solver, moment storm, adjusted. Ultimately, maps 3D models presented stakeholders namely, management, protected area operatives, road tourist infrastructures’ management order enhance resilience strategies environmental protection.
